The invention relates to the technical field of image processing, in particular to a method and system for detecting water on urban roads based on image processing, comprising: acquiring an infrared image of a road surface, denoising the infrared image to obtain a reconstructed signal, The temperature grade of the pixel points is used to determine the temperature grade threshold for dividing the road water accumulation area, obtain the edge image of the road water accumulation area, and obtain the area index and depth index of the road water accumulation area. The system of the invention has low overall cost and high accuracy, can accurately extract road surface segmentation images, accurately obtain the water accumulation degree of the road surface, and effectively provide real-time road water accumulation information for relevant departments. |
